Nano- and Micro-Patterning of Silk Fibroin Films for Biomedical Optical Applications

Nano- and Micro-Patterning of Silk Fibroin Films for Biomedical Optical Applications 

Combining silk films with nano- and micro-patteming technologies can also bring some optical properties to silk films. This is an approach similar to lithography. The final products are usually in the form of optical lenses, a microlens array, a two-dimensional diffractive optical element, a diffraction grating, and a white-light 

Fiorenzo et al. reported a simple modified soft-lithography process to construct a nano- and micro-patterned silk fibroin film [9]. They claimed the creation of the smallest nanopattems in silk fibroin films. Using this technique, high quality films containing intricate 2D and 3D nano- and micropattems were fabricated.
